tank 4 is supported from the front wall I of the box by a shank 5 in the form of a pipe section extending through the box wall and connected at its opposite ends to the tank 4 and the faucet 3, respectively. The conduit section 5 is preferably threaded on its outer side to receive clamp nuts G, 1 for clamping the shank in place in the box wall I. A washer 8 is employed with the clamp assembly to close the box opening through which the shank 5 extends.

The top of the tank 4 is closed by a cover casting 9 fitting over the top of the tank as detailed in Fig. 2. This casting is provided with two boss formations I3, I I both cored to provide passages I2 and I3, respectively. Theoutlet end I4 of the coil 2 is connected with the passage l2 for the flow of beer from the coil 2 into the. tank il. A clamp nut I5 is employed in the con-v nection as shown. The incoming beer is led to the bottom of the tank 4 through a conduit section I5 located within the tank 4 and connected at its upper end to the passage I2. The lower end I-'I of the conduit I6 is at the bottom of the tank 4 and is there fashioned to dischargethe beer in a smooth stream circumferentially of the tankll Vand relatively close to its upright cylindrical wall. This is shown in Fig. 3, and the purpose of the arrangement is to lessen, if not completely eliminate, turbulence or agitation of the beer within the tank 4. Y,It isY to be understood in this connection that the beer is forced through the system by the gas pressure thereon within the keg from the gas content of the beer as employed for its carbonation and the additional gas pressure which is usually supplied to the lkeg through its tap rod clamp as in beer drawing systems of the type in question. The tank 4 may be tapered upwardly to aid in quieting its liquid content as shown in Fig. l.

Also located within the tank 4 is a tube section I2. This 'tube section is preferably in the form of a coil or helix to further control the fdow of the beer to the faucet 3 and has its lower or inlet end I3 adjacent to the bottom of the tank l and its upper or outlet end 20 connected into the passage I3 in the boss II. The diameter and length of the coil I8 is such as to sufficiently retard the speed of the ow under the pressure within the keg to effectuate a controlled discharge at the faucet 3. In practice, the diameter of the coil I8 is relatively smaller than the diameter of the cooling coil 2.

As detailed in Fig. 2. the passage I3 extends to the outer end of the boss I I which at this endV is enlarged and internally threaded for connection with the adjacent threaded end of the shank 5. The latter seats against a shoulder within the boss, there being a rubber gasket 2I between the parts to seal thejoint as shown. Locatedl within the shank 5 is a tube element 22.` The latter extends completely through and beyond the' opposite ends of the shank 5 and abuts against a rubber gasket 23 located within the boss II when the parts are clamped together as shown in Fig. 2. Here, the passage I3 has an enlarged section I3a to receive the adjacent end i of the tube 22 and mount the gasket 23 at the end thereof. The'tube element 22 has a'diameter less thanthe inside diameter-of the section 5 to u Yprovide a longitudinally extending passage 24 between them. The tube 22 carries a `smaller tube II in the passage section I3a.

extends through the' gasket 23 and seats against 25 as a continuation thereof within the boss The tube 25 n chamber 35 therein.

a shoulder 26 between the passage I3 and its connected section I3a. The tube 25 is enlarged at its outer end to abut the shoulder 26 and also to provide a seat for the gasket 23 as shown.

The cover casting 9 is provided at one side of the coil I3 with a passage or port 21. This port serves to connect the upper end of the tank 4 with the boss passage I3@ about the outer side of the Ytube element 22.v Here, the' tube element 22 is reduced in diameter as at 28 to connect the port 2l with the passage 24 between the tube 22 and the shank 5. This port 2'I is concerned with the atomizing action of the faucet 3 to control the amount and character of the foam which is placed on the beer which is drawn into the glass or other dispensing container from the faucet 3. The upper end of the tank 4 is divided from the port 2`I'by a partition wall and check valve mechanism to be later described.

As heretofore stated, the lshank 5 extends through and beyond the box wall Il to the front side thereof and is provided at or adjacent to its end with a flange 29 for a union nut 3l)` which connects the faucet. 3 to the outer end of the shank 5 and clampsY the tube 22 against the gasket V23 as shown in Fig. 2. yThe faucet 3 has la tubular extension 3| threaded on its outer side for engagement by the union nut 33. A gasket 32 is interposed between the flange 29 and the extension 3l to' provide a leakproof joint.' The outer end of the tube 22 is threaded and screws into the extension 3l at 33, whereby the drawing action of the union 3i) on the faucet 3 will clamp the tube 22 against the gasket 23 andthe tube 25 against the shoulder 25 to seal the joints in "this part of the assembly.

The faucet 5 Yis Vpreferably in the form of a casting having an outside body or case 34 providing a longitudinally disposed-liquid receiving The upper end of this chamber is closed by a screw plug'or cap member 36 which has a tubular portion 3l extending into lthe chamber and in screw threaded connection Ytherewitl'i as shown in Fig. 2. The body 34 of Athe faucet has a pair of passages 33, 39, one connecting the tube 22 with the, lower end of the chamber 35 and the other connecting the passage 24 with the upper'end of said chamber. The connection of the passage 39 with the upper end of the chamber 35 is through a number of radial portsfi in the cap extension 3l. These ports open into an annular kgroove 4I in the cap extension" 3l to connect the passage 39 with the ports in any rotative position of thecap element36 when seated against .the faucet body.

Located within the faucet chamber 35 is a valve carrier shaped tohave a body wall 43 and spaced; but parallel, cross-members 44, 45. A The mechanism to be presently described to open the valve members, also to be later described, is located in the space between the cross-members 44, 45. The wall member 43 of the carrier 42 conforms to and has a loose sliding fit within the chamber 35 as shown in Fig. 4. The carrier 42 is not as long' as the chamber 35 and hence may be slid endwise thereof to open and to close 'a main valve member 4l ltobe next described.

' The valve member 4l is at the lower end of the carrier eijand cooperates with a valve seat 48 providedwithin the' faucet housing 34 between the chamber 35 and the discharge spout 49 of 'i said housing. The valve member 41 is resilient,

` being preferably of rubber, to close the connection'between the spout 49 andthe chamber 35 2,`B2-.7,444 when 4the val-ve member is pressedagainst its seat vd8. A coiled expansion spring 5i) within the capte uperforar-is this This spring :normally presses the carrier 42 downwardly having bearing at its lower Vend on the crossmember 44 and at its upper end against cap 36. `The cross-member H'carriese boss or projection 51 to center the spring.

To lift the valvefmem-ber 41=1from Vits Vseat 48, I provide` a Amanually operable ,turning arrangement comprising `a shaft ijournalled 'in lthe side Walls of' the faucet housing 34 and' provided intermediate its end s with a cam projection 5310e- .tween the crossfmembers 44', 45 as shown in Figs; 2 and 4. The projection 51'` is located directly beneath the upper cross-member 44 and whenraisedV or rocked upwardly willY lift the valve z riember 41 Yfrom vitsse'at .48'. 'Turning the shaft 52,121., the opposite 'direction lowers thefproiection '5.3 and the. spring. 5.11 closes the valve memberl.

IAheshaft52 is mounted in a packing structure v54 where it extends out. Qf the valve housing as shown in Fig. 4, is equipped at its outer end with an. operating handlej55 having at its upper end asuitable grasping knob 5,6 as shown in Eig. l. To open the valve 41, thehandle 55 is drawn forwardlythat is, towards theV operator in the .direction indicated by the arrow. a in Fig. 2. To close the valve Vmemberl the handle is moved in the reverse Adirection 4and. the 'valve .member is seated. whenlfthe handle member 55 reaches a substantially upright` position asshown in Fig. 1,. Y

To, control the foaming. oi the beer, I provide the following mechanism.

' An atomizing, tube 51 issecured. tothe lower endof the valvecarrier. 42. This tube is preferably centrally located with respect to theV valve member 41 and extends through and below the .samelnto the nozzle 49.: as shownin Fig. 2. The

Vtube 51 is providedwith aflow passage 58 of relatively small diameter. closed at its upper end with- .in thevalve 41. by an-endwalL 59. Herethe tube Y5.1.is providedwith a number of. relatively small, radial apertures or openings 6i)y which connect the `flow passage :58 .of the ltube-with a chamber 6| .for the liquid inj the faucethousing above the Vvalve 4.1. The tube "5-1.is open at itslowerend land discharges into the now passage" 62 which the nozzle 4Qv provides 'belowv the,valve 41. It will be noted that .thetube A51is smaller in diameter Vthanthe nozzlei49fso that both the valve 41v and "the tube 51. may respectivelyvdischarge the liquid controlled therebyinto said nozzle, the discharge from the valve 41 being about the tube. The chamber 6 Lwhich isvat the upper end1of the tube 51 is located within Aa xturehaving a valve seat 64 for a supplemental valve member 65,

also ofq rubber` or other desiredcushion and seal- .ingmaterial Y The fixture G3 is in the form `of a vbody element Shaving a tubular projection extending into the Vvalve carrier 4.2'. below the cross-member 45and threadedly connectedwith said carrier. The pro- .J'ectionlt` provides a chamber61 abovethe valve seat 64.and houses ay coiled Aexpansion springV 68 which;` normally closes the valve member 65 against its sea-t 64.` The. chamber 61 connects withgthe passage Sliwhenthe valvernember 65 vis opened and liquidentering the faucet chamber "351through-the passage-39-.flows:into the tubev 51 -for atomizationthereby within the; nozzle 49.

The, pressure ofthe gas on the-beer forcibly dis- 3 charges it from the tube Vdrie to theasall diameter of itube 'passage f5@ :andthe 6l, the liquid stream is broken up .in a" marmer for discharge from .the cuter end of Tthev tube 5-1 in an `atomized` spray. This allows the'foceluded :gases 'within 4the liquid `-to fom a richt creamy foam which on discharge from the 48 produces the desired collar on `the solid col umn of beer rlrst discharged into the drin-lung glass or other container from the faucet 3. "Itflls to be understood, that the glass i'siirst nlled with solid beer through the main valve-'member 541, the supplemental valve member being closed at this time by its spring BS;

The valve member 65 is-carried by a valve stem 69 within the spring B8 and extending a1; its u1 per endl into the space between the cross-members 44, 45, through an enlarged opening lln thebross-member 45. -The uiiperend` of the valve stem 68 is headed as at 1l, and this `head hasr tapered walls as shown. A lever 12 engages the headr 1| and has a fulcrum projection 13 on its under side to engage` the cross-member 4S. The lever 12 is fashioned to normally stand. at an angle or incline when the'suppleineiital valve 65 is closed as shown in Fig5 2. The downward pressure of the spring SBV on the4 valve l Gt' nor*- mally holds the lever 12 in this positionY withlts fulcrumV projection 13 seated against the crosswall 45.

The Vwider end of thelever 12- is ini'the path of t-he caml projection 53 and when the shaft"52 isv turned `to force said projection against the lever the latter is rocked upwardly to lift the valve member- 65I from its seat 64. To accomplish this, the handle member 55 is swung away from' the operator, the direction being indicated bythe arrow bin Fig; 2v;

The partition Y wall heretoforev referred to is shown at 14 in Fig. 2. This Wall member extends across the top of thetank tand divides the tank from the port 21. The cover element 9 is fashiioned toeXtend'above 'the Vtank to provide a. chamber 15 above the partition wall 14. The tubes I6 and I8 extend through the partition wall 14 to reach their respective passages l2, I3 in the cover element 9 as shown. These tubes have a suiciently tight t in the partition Wall T4 so that the liquid in the `tank below thepartition Wall is prevented from owing into the chain.- ber 15 except through the non-return check valve element 16. The partition wall 14 has a'port 11 extending therethrough to connect the portions -ofthe tank 4 on opposite sides of the partition wall andto mount the valve element 18. The latter is'self' closing being gravity and pressure controlled and when closed seats against; a ta pered seat aboutthe upper edge of the port opening 11. The head of the valve 1611's tapered'to conform to this seat and is located within the chamber 15 so that anyincrease inpressure'within said chamber will closethe valve and prevent turbulence or'agitation ofthe liquid content of the tank 4' belowthe partition wall. With the faucet 3 and the adjoining yportion of the shank 5' at room temperature, being'out of the cooling influence ofthe refrigerant within the coil box, there is the likelihood of the gas pressure within the faucet being increased due to the higher temperature -to which the faucet and the-shank are exposed. The check'valve 16 closesoffthe tank4 from'th'is increase in-pressure on the foam providingV side of the apparatus and noobjection-ablereactionoccurs on the liquid-within the tank-'4-` below thepartition Wall14to disturb the drawing of a solid column of beer from the tank through the main valve 4l'. On this side of the apparatus the retarding influence of the coil I8 within the tankr4 lessens the opportunity of this increase of pressure within the faucet and the shank disturbing the liquid content of the tank with which the coil connects. If desired, a check valve, as shown in Fig. '7, may be incorporated in the fio-w line between the tank 4 and the main valve 4l'. The structure disclosed in Fig. '7 will be described later.

r The checkvalve i6 has the further advantage of reducing the possibility ofI gurgling at the faucet 3 on opening the supplemental valve S5. This is due to the fact that free gas is not so likely -to collect because of the liquid column which these valves when closed conne between them.

The check valve 18 has a dependent stern T8 extending through the port 'l1 intothe tank 4. This stem has a sliding fit within the port to guide the valve 16 in its opening and closing movements. A cotter pin 19 or other equivalent stop is carried by the stem 18 below the partition wall 14 to limit upward movement of the `valve 1S and prevent its displacement from the port 'l1 during vthe handling as well as the o-peration of the device,

As before stated the flo-w of liquid from the tank 4 to the portion of the faucet 3 above the valve 41 is through the port 2T and the connected passage 24. When the supplemental valve 65 is o-pen the liquid may flow from the tankl 4 into the faucet through the port 21 due to the pressure of the incoming liquid raising the valve and .the reduction of pressure on the upper side of the valve. When the supplemental valve is closed, the check valve 1.5 closes by the pressure of the liquid column thereon aided by gravity, the Valve 16 operating vertically as shown. I might remark at this point that the stem 'i8 of the check valve 1S is grooved longitudinally so that the liquid may ilow past the valve into the chamber l when the check valve is raised. Any

increase in pressure within the liquid column between the faucet and the chamber i5 will, as before stated, act on the valve 18 and keep it closed.

TheY mechanism shown and so far described operates as follows: After the cooling coil 2 has been connected with the keg, the pressure within the keg will ll the system with liquid up to the valves 4i and .65. The latter are closed at this time and the system is Yready for use as shown in Figs. l and 2. the handle 55 is drawn forwardly and a solid flow of beer is discharged from the faucet 3 into the receiving glass or lother receptacle without agitation due to the control as aorded by the tank 4 and the coil I8. When the receiving receptacle has been filled to the desired extent, as for example up near the top, the ow of solid beer is cut off by the operator returning the handle 55 to its upright position as shown in the drawings to close the mam van/e t?. The Smau amount of agitation produced within the beer as it is discharged into the glass will not create much of a foam on the top of the column. To add the desired foam orcollar, the operator moves the handle member 55 rearwardly in the direction of the arrow b in Fig. 2 to open the supplemental .valve 65. The beer is now atomized by the tube 5l and a creamy and relatively thick foam is deposited on the solid beer in the receiving receptacle. This enhances the appear- To dispense a quantity of beer, f

Voi .the outer tube 82 with thefmernber 89. Yclosing check valve 96 is mounted in the partiance and improves the taste of the beverage. Returning the handle 55 to its upright position closes the valve and the apparatus is ready for the next draw. Y Y

When applying my invention to a direct draw system the structure-is constructed as shown in Fig. 5. Here indicates a tap rod assembly the lower portion 8l of which is linserted into the keg through a suitable tapping fixture not shown. The lower. portion 8|V constitutes .in eifectthe tap rod for the assembly and is comprised of an outer tube B2 and aninner tube 83. These tubes are of different diameters and are arranged one within'the-other to provide an annular liquid flow passage 84 therebetween. A plug element 85 closes the lower ends of both tubes and is provided with a series of radially disposed inlet ports or openings 85 which connect the interior of the keg to the inner tube 83. The upper end of the latter is connected with the flow passage 84 in any suitable manner, the particular arrangement shown in Fig. 5 constituted in having the upper end of the inner tube 83 terminating short of the upper end of the outer tube 82. In this way liquid flowing into the inner tube 83 at its lower end may flow into the passage 84 for entry into the main draft tube 81 which extends into the passage B4 from a head casting 88 at'the upper end ofthe draft rod assembly as shown in Fig. 5.` A cylindrical member 89 connects the head 88 to the tap rod section 8l and provides aV liquid receiving chamber 90 therebetween. The tube 81 Vextends through the chamber 88 and has its upper end extending into and having a tight t in a passage 9! inthe head 88. This passage 9| opens into a joining passage 92 which corresponds to the passage i3 in the faucet structure 3 of Fig. 2. The passage 92 supplies liquid toa tube element 22a embodied in the faucet'device 3a and serving the same purpose as the tube 22 in the faucet 3.

The 'head 88 has another passage 93 Vserving the same purpose as the port 21 of the device shown in the previous figures and this passage 93 connects at its-lower end with the chamber and at its upper end with a passage 24a in the faucet device 3a. The passage 24a serves the same purpose as the passage 24 in the faucetl 3. To prevent an increase in pressure in the liquid column between the faucet 3a and theY chamber 98 disturbing the vliquid column within the tap rod sectionl 8|, I provide a check valve arrangement at the lower end of the chamber 99 as shown in Fig. 5. This check valve arrangement serves the same purpose as-the check valve device heretofore shown and described and is constructed as follows:

vThe device comprises a partition wall 94 which divides the chamber 9G from the upper end of the inner and outer tube assembly of the tap rod section 8l. The partition. 94 is supported above `the upper ends of this tube assembly by a coupling element 95. The latter not only supports the partition wall 94, but connects the upper end A self tion wall 94 at a port 81. in the same manner as shown in the previous figures. This check valve .95 is located to one side of the tube 8l which extends through the partition wall 94 with a sufficient tight t to prevent 'liquid flowing into ythe chamber 99 except through the. check valve as before. This check valve has a grooved stem 98 which guidesthe check valve in its opening and closing movements and also provides for the eine geen .-.Eea-Cherie. vairefl- .i comprises 'a valve member |04 'and a seat therefor .Qi iff. 5,: up; am: ugh-.them mOn-wallirlhentthe check valve also .has a mul. check valve is open.
